Facebook is already the most popular online hangout for telling the world everything you're doing, everything you've ever done, and everything you have yet to do. With users constantly updating their status to tell the world of their most enthralling daily activities, it only makes sense that the world would desperately want to know what music you're listening to. And not just that staid, two-dimensional "Favorite Music" section. Oh, no. The world moves much too fast for profile updates. The human populations move in real time, and so should your music updates. Now, thanks to a plug-in called "Facebook Listening to v1.0," the world can finally follow your every browse through your online music library.

Basically, the way it works is you've first gotta add an application called "I am Listening To" to your Facebook page. Once you do that, this long page of instructions and features will pop up, but the most critical thing is the random Facebook User ID and "Secret Key" that they'll give you. You'll need this in order to activate the plug-in, which you can download here. What happens next, dear reader, is nothing short of magic. What the plug-in does, if you want it to, is update your Facebook status as you surf through your library, so all of your friends and family will know what you're listening to at any given moment. You can also choose to load your playlist library directly into your profile, and examine (read: rip apart) your friends'obviously inferior music tastes. Most spellbindingly, both your music status and your embedded playlist will be updated automatically-even if you're not logged in (*gasp!*).

All in all, it's a pretty cool application, for those brave enough to use it. The potential for embarrassment is pretty obvious (do you really want Aunt Rhoda knowing how many times you listen to Enya every day?). But then again, no less embarrassing than most of the stuff that happens in the Wild Wild West of Facebook. At least in this case, the upside of showing off your music taste and your infinite coolness far outweigh any possibly relationship or job-destroying revelations.
